Definitions

  • This invention relates to ground-reinforcement panels, and multi-panel, ground-decking arrays incorporating them.
  • PSP can be supplied and applied to the ground surface in a continuous roll, but the more it is used (and thus the more it becomes deformed) the less chance there is that it can ever be recovered by simply rolling it up again.
  • the genesis of the present invention lies in recognizing that the key to the problem here confronted and solved lies in evolving an interlock mechanism for use between adjacent, heavy-duty ground-reinforcing panels which is simultaneously sturdy enough to withstand the sometimes extreme horizontal stresses imposed upon it by vehicular traffic, and yet which is flexible enough to allow considerable vertical displacement of one panel out of the plane of its adjacent panels to such an extent that simultaneously on the one hand it is possible for the ground-reinforcement to accommodate itself to significant undulations in the underlying terrain and on the other hand it is possible for the ground-reinforcement to arrive at the site in a roll, to be laid out upon the ground surface by simply unrolling that roll, and afterwards to be recovered by rolling it up again.
  • a generally-planar ground-reinforcement panel for use in an articulated sequence or array of such panels, the boundaries of said panel including at least one pair of parallel rectilinear edges, said pair of edges being provided with respectively a number of male interlock members projecting therefrom in the plane of the panel and a corresponding number of female interlock members recessed therein, the arrangement being such that (a) the male member(s) on the edge of the panel may be forcibly but detachably engaged in a direction vertical to the plane of the panel with the female member(s) in the edge of another such next-adjacent panel but cannot be disengaged therefrom in the horizontal plane of the panels, and that (b) the male and female members are so constructed that when inter-engaged they are capable of limited rotation with respect to each other so that the panel is interlocked hingedly with a similar next-adjacent panel.
  • each male member associated with one of the edges of the panels comprises a spigot projecting longitudinally from its associated panel-edge and lying in the plane of said panel, said spigot at or adjacent its end remote from the panel-edge being provided with at least one transverse, generally-prismatic lug lying also in the plane of said panel, and each female member associated with the other edge of the panel comprises a generally-prismatic chamber recessed there -within and disposed substantially parallel thereto, which chamber is able to accommodate the transverse lug(s) upon the spigot, at least one or other of the generally-prismatic lug(s) and chamber being truly cylindrical or at least part-cylindrical so that the lug(s) and the chamber may be rotated the one relative to the other about their common prismatic axis.
  • generally prismatic is used herein to embrace not only its obvious meaning of a multi-faceted generally-cylindrical prism but also even (and indeed especially) the extreme case where the number of facets approaches infinity and one arrives at a truly cylindrical (or part-cylindrical) surface.
  • the crucial requirement for the purposes of the present invention is that the lug(s) on the spigot should be accommodated within the chamber at least to some extent rotatably therewithin, and that the lug(s) and the facing chamber surfaces should co-act as bearing surfaces to hold the adjacent panels together even against quite considerable tensional stresses in the horizontal plane.
  • Those two requirements can be met when, as previously envisaged, only one of the mating surfaces of respectively the lugs and the accommodating chamber is truly cylindrical, whereas the other is a multi-faceted prism proper.
  • both said lug(s) and said chamber shall have truly cylindrical co-acting surfaces, at least in the direction in which horizontal tensional stresses will during normal usage be applied to and resisted by these co-acting bearing surfaces.
  • the generally-prismatic chamber within one plate-edge communicates with the edge of the plate via a relatively-narrow slot in said edge, through which can pass only the spigot but not the lug(s) of the male member in a range of angular orientations between the prismatic lug(s) and the prismatic chamber.
  • the prismatic chamber also communicates with at least one face of its associated panel via an elongate aperture parallel to the panel-edge, said elongate aperture having substantially the same length as that of the prismatic lug(s) and through which said lug(s) can be introduced into said chamber.
  • the elongate aperture in the face of the panel and the relatively-narrow slot on the edge thereof communicate with each other on at least one of the faces of the panel associated with the female member(s), so as to permit introduction of the spigot-mounted lug(s) within the chamber, and means are provided whereby after insertion of the spigot-mounted lug(s) within the chamber said lug(s) are to at least some extent hindered from exiting from said chamber when the respective next-adjacent panels lie in substantially the same plane.
  • the male and female members must lie within the plane of the panels and be inseparable in that plane, while also being both inter-engagable and disengagable (when desired) in directions perpendicular to that plane.... but additionally it is also necessary to provide means for hindering unwanted accidental disengagement during normal use.
  • the panels shall be completely or substantially-completely (e.g. with the possible exception of the male member) formed of injection-moulded plastics material, e.g. a fairly rigid but to some limited extent resiliently-flexible and very desirably fire-retardant grade of a suitable plastics material, including for instance polyvinylchloride, polyethylene or polypropylene, but above all acrylonitrile butadiene styrene (ABS)
  • ABS acrylonitrile butadiene styrene
  • disengagement hindering means in the form of projections or lips arranged along one or both sides of the elongate aperture which reduce its effective width to somewhat less than the diameter of the cylindrical lug(s), so that the lug(s) can be introduced within the chamber (even when both next-adjacent panels are lying in substantially the same plane) only by forcing them through the elongate aperture against the resilient bias of those projections or lips, thus by making a force-fit between the male and female members.
  • the male member once thus mated with the female member cannot easily slip out of engagement, since it then can be disengaged only by overcoming the retaining bias of the same projections or lips along the elongate aperture.
  • the lips are omitted and instead the disengagement hindering means take the form of an integrally-moulded, upstanding, resiliently flexible catch which is flexed into a recess so as to admit the male member into mating engagement with the female member but thereafter springs back to hook over the upper surface of the male member- and thereby hinder it from exiting from mating engagement.
  • the whole arrangement should be symmetrical. Therefore the spigot of the male member(s) projecting from one panel-edge and the access slot of the female member(s) recessed into the other panel-edge will normally be both directed at right-angles to said respective edges, while the end of the spigot is provided with two similarly-dimensioned but oppositely-directed generally prismatic lugs, one on either side thereof, the prismatic axis of said lugs being at right angles to the spigot-axis but in the plane of the panel so that when the male and female members on next-adjacent panels are interlocked the prismatic axis of the lugs is substantially co-incident with the axis of the prismatic chamber.
  • both the spigot and the two transverse lugs mounted thereon are formed of circular cross-section rod having the same diameter.
  • the spigot and lugs are formed of metal, e.g. steel rod having an adequate tensile strength for the intended usage.
  • each lug along its prismatic axis transverse to the spigot-axis will very conveniently be substantially the same as the width of the slot through which the spigot enters the chamber.
  • the panels of this invention can be laid and lifted manually, one at a time; and indeed if a panel in a sequence or array becomes damaged it will be necessary to replace it by hand. It is nevertheless one of the important objectives of this invention to enable and facilitate the laying and lifting of a sequence of articulated panels in a roll, and for that purpose they must be capable of tilting hingedly relative to each other.
  • one of the pair of parallel edges is associated only with one or more male member(s) projecting therefrom and the other of those edges is associated only with one or more corresponding female member(s) recessed therewithin.
  • edge-communicating slot is recessed into its associated panel-edge, sufficiently to permit rotation of the spigot and lug(s) relative to the chamber through an angle of more than 90° (between horizontal and vertical planes) and preferably of between 135° and 180°.
  • the panel will preferably be bounded by two pairs of parallel rectilinear edges, and thus be rectangular in plan. It is desirable that there should be a plurality of male and female members spaced apart symmetrically along each rectilinear panel-edge, conveniently in pairs or larger multiples of two.
  • this invention has been primarily concerned with the interlock mechanism between next-adjacent panels in a sequence or array, and indeed it is centred there - but it does of course have other features of a highly preferred nature besides those relating simply to that interlock mechanism. While it is broadly-true that any ground-decking articulated panel system when interlocked by the mechanism already described should be capable of withstanding the horizontal tensional stresses imparted to it by vehicular traffic thereon, it will be appreciated that there are various possibly-differing requirements for the exact nature of the panels best employed for one kind of end-purpose or another.
  • a generally-planar ground-reinforcement panel of the kind hereinabove disclosed, which comprises a rectangular, generally-planar, substantially rigid framework and an upper decking plate supported by and secured to one side of the planar framework, the framework comprising a rectangular peripheral frame and within said frame a number of load-transfer struts intersecting with the peripheral frame so as to distribute load applied to the decking plate appropriately across the entire framework and via the peripheral frame and the intersecting load-transfer struts to the underlying ground upon which the panel is to be placed.
  • decking plate prefferably integrated with the framework, as by moulding the framework from plastics material with the decking plate in situ.
  • the decking plate (on its outer surface) should be relatively non-reflective. From whatever material the decking plate is formed its surface therefore should be roughened or otherwise treated to reduce its light reflectivity.
  • the currently preferred decking plates are those formed of appropriate aluminium alloys - and the upper surface of such aluminium plates is advantageously rendered relatively non-reflective by surface-indentation and/or embossing of that surface with a so-called "chequer-plate" pattern.
  • ground-reinforcement panels described above are for many or even most purposes perfectly satisfactory as they stand, but when they are expected to carry very heavy traffic, especially over ground of suspect compressive strength, they can be further improved in their load-bearing capacity by providing the lower surface of the panel (remote from the decking plate) with a soil compression unit.
  • soil-compactor spikes will preferably be generally-pyramidal, a term which includes other multi-faceted, even conical and/or irregular shapes akin to a true pyramid, and no matter whether the facets thereof be planar or instead either somewhat concave or convex.
  • the ground compression unit will preferably be a moulding which on its lower surface provides the multiplicity of soil-compactor spikes but on its upper surface is shaped to fit snugly, and at best exactly and completely, within the interstices between the peripheral frame and intersecting load-distribution struts underneath the panel framework, and to abut against the underside of the decking plate secured thereto.
  • the upper surfaces of the ground compression unit and the underneath surfaces of the panel framework will very desirably be provided each with co-acting means whereby the compression unit may be snap-fitted below the panel beneath the panel.
  • the soil compression unit will advantageously be moulded from a rigid-foamed plastic material, e.g. rigid polyurethane foam, and then will desirably be encased in water-impermeable sheet-material, e.g. a blow-moulded polyvinylchloride skin.
  • a rigid-foamed plastic material e.g. rigid polyurethane foam
  • water-impermeable sheet-material e.g. a blow-moulded polyvinylchloride skin.
  • the invention of course extends to an essentially uni-dimensional sequence of such panels, adapted to be rolled out onto the ground and thereafter rolled up again so as to lift it from the ground.
  • Figure 15 is an underneath plan view if part of a soil compression unit generally similar to that illustrated in Figure 14 but with a preferred pattern of soil-compactor pyramidal spikes arranged thereon;
  • Figure 16 is a schematic, vertical part-sectional view through a heavy-duty panel which is intended merely to illustrate the preferred manner in which the soil-compression unit is fitted snugly within the panel below the panel-decking plate.
  • FIG. 1 this rather schematically shows a ground-reinforcement panel generally indicated 1 of rectangular outline, typically 2 feet wide by 1 foot long (or comparable metric measurements, e.g. 50 centimetres wide by 25 centimetres long) which is bounded by rectilinear edges indicated 2, 3, 4 and 5.
  • edges 3 and 4 Associated with the other edges 3 and 4 (which are also arranged at right-angles to each other, but parallel to respective edges 5 and 2) there is a corresponding series of female interlock members 7, four of them spaced along and recessed within edge 3 and eight along and within edge 4.
  • an essentially uni-dimensional sequence of such panels (1, 1', 1"...and so on) is formed in the direction of arrow A by inter-engaging the T-shaped male members 6 on panel 1 with the female members 7' on panel 1', then the male members 6' on panel 1' with the female members 7" on panel 1", and so on.
  • the respective male and female interlock members (of the panels, sequences and arrays of Figure 1 to 3) are shown in more detail, but still only schematically, in the enlarged plan view of the near-abutting but not yet interlocked edges 2 and 4' shown in Figure 4 and the vertical cross-sectional view therethrough (taken on the line X-X in Figure 4) which is shown in Figure 5.
  • the male interlock member 6 projecting from panel edge 2 comprises a spigot 20, lying within the plane of panel 2, which spigot 20 at the distal end thereof carries transverse lugs 21, 22 also lying in the plane of panel 2.
  • the female member 7 recessed within panel edge 4' comprises a cylindrical chamber 23, with its axis parallel to panel edge 4' and able to accommodate the end of the spigot 20 and transverse lugs 21, 22.
  • the cylindrical chamber 23 communicates with edge 4' through spigot-access slot 24, and it also communicates with the upper face of panel 4' through elongate aperture 25 within which and running down each side thereof are respective resiliently-flexible lips 26 and 27.
  • Figures 8 to 11 show views (essentially the same as those depicted in Figures 4 to 7, and in which the same reference numerals are used to identify similar parts) of an alternative embodiment, possibly better suited for fabrication by injection moulding techniques, in which the lips 26 and 27 (in Figures 4 - 7) are omitted, and instead there is provided an integrally-moulded, upstanding, resiliently-flexible catch 28 at the mouth of a recess 29 into which the catch 28 is forced back when the transverse lugs 21, 22 are forced downwardly into mating engagement with the chamber 23, but then springs back to hook over the lugs as shown in Figure 11.
  • the rectangular panel generally indicated 1 is a framework comprising a rectangular peripheral frame 30 and within said frame a number of load distribution struts 31, which may be of any suitable design but are here shown in their currently-preferred arrangement of two diagonal struts 31a and three equidistantly-spaced intermediate struts 31b, parallel to edges 2 and 4, intersecting with another three equidistantly-spaced intermediate struts 31c.
  • All of these struts 31 intersect with the peripheral frame 30, while the two diagonal struts 31a and the two median struts 31b and 31c intersect with each other at a central boss 32.
  • panel-edges 2 and 5 are provided with a series of projecting male members 6, while panel-edges 3 and 4 have a corresponding series of female members 7 as recessed therewithin.
  • the intersecting struts 31 have the same depth as the peripheral frame 30 and thus any load applied to the upper decking plate (not here shown) is transmitted through both the peripheral frame 30 and the intersecting struts 31 to the ground-contact surface created by the bottom of the frame 30 and struts 31.
  • Figures 14, 15 and 16 show a further elaboration of the panel of Figures 12 and 13.
  • the panel of Figures 12 and 13 can be additionally provided with a soil-compression unit, here shown in an exploded view and generally indicated 40, which of course in use is attached immediately adjacent and beneath the ground-contact faces of the frame 30 and intersecting struts 31.
  • the soil compression unit 40 is provided with rows of downwardly-pointing pyramidal spikes 41, which when the panel lequipped with the soil-compression unit 40 is put under load penetrate the under-lying ground (not shown) and compress and compact it to improve its load-bearing capacity.
  • the soil compression unit 40 shown in Figure 14 has rows of pyramidal spikes 41 which run in phase with each other, but preferably such rows of pyramidal spikes are arranged with each row out of phase with the next adjacent row by one half of one pitch, as illustrated in Figure 15.
  • the upper surface of the soil-compression unit 40 may be planar (as it might be assumed to be in Figure 14) it is preferred that, as shown in Figure 16, its upper surface shall be moulded to fit snugly within the interstices between the peripheral frame 30 and the intersecting struts 31 in the panel frame-work, and indeed effectively to fill those interstices so that the uppermost surfaces of the moulded soil-compression unit 40 abut against the under-surface of an aluminium panel decking plate 42, thus ensuring that loads applied to the latter are transmitted as evenly as possible to the soil compression unit.
